Whether it’s a magazine cover, high fashion photo shoot or a day at the beach, celebrities have never been shy about leaving their tops behind.

Alessandra Ambrosio gave fans a special Valentine’s Day gift this year by sharing a topless photo of herself on Instagram. Peering over her back and pink “hottie” bottoms, the Victoria’s Secret Angel wrote, “Who is ready for #valentinesday?”

Kate Upton also posed topless on several occasions — with the most recent being her second consecutive Sports Illustrated swimsuit issue cover. The 20-year-old bombshell also went topless for Vogue Germany and Cosmopolitan in recent months.
